4.  Halkın Demokrasi Partisi (People's Democracy Party, hereafter referred to as “HADEP”) was a political party which was established on 11 May 1994. It opened branches in 47 cities and in hundreds of districts. The applicants were members of HADEP and they held executive positions within the party.
5.  On 29 January 1999 the chief prosecutor at the Court of Cassation brought proceedings before the Constitutional Court and demanded that HADEP be dissolved. The prosecutor argued that HADEP had become a “centre of illegal activities against the integrity of Turkey”. In support of his allegations he referred to a number of pending criminal proceedings against HADEP members, including the applicants.
6.  In its decision of 13 March 2003, which was published in the Official Gazette on 19 July 2003 and thus became final, the Constitutional Court dissolved HADEP[2]. The Constitutional Court based its decision on sections 68 and 69 of the Constitution and sections 101 and 103 of Law no. 2820 on Political Parties. In arriving at its conclusion, the Constitutional Court took account of the actions and statements of certain leaders and members of HADEP, including the applicants. As an ancillary measure under section 69 § 9 of the Constitution and section 95 of Law no. 2820, the Constitutional Court banned the applicants and 18 other HADEP members and leaders from becoming founder members, ordinary members, leaders or auditors of any other political party for a period of five years.
7.  Details of the criminal proceedings which had been brought against the applicants and which were referred to by the Constitutional Court in its decision are detailed below. In the opinion of the Constitutional Court, the actions of the applicants which are set out below, as well as the actions of the remaining 18 HADEP members and leaders, proved that a link existed between the applicants, HADEP and the PKK[3].
8.  These applicants were executive members of HADEP's Malatya branch. In 1998 criminal proceedings were brought against them for lending assistance to an illegal organisation, namely the PKK, contrary to Article 169 of the Criminal Code then in force.

Banners had also been displayed on HADEP's premises expressing discomfort with the arrest, as well as denigrating the Turkish state and actions of the Turkish security forces. People present on the premises had also been allowed to watch PKK propaganda broadcasts on Med TV. Various pro-PKK newspapers and journals, as well as photographs of various PKK members who had been killed in operations, were also recovered from the premises.
9.  These applicants were subsequently tried by the Malatya State Security Court and were found guilty on 16 December 1999. They were sentenced to three years and nine months' imprisonment and their conviction was upheld by the Court of Cassation on 4 December 2000.
